The Duchess of Cambridge showed off her dancing skills as she enjoyed a twirl with Paddington Bear on Monday.
Pregnant Catherine joined her husband, Prince William at Paddington station in London for a charity event in conjunction with the new Paddington bear film.
The mother-of-two has been keeping a low-profile in recent weeks as she battles severe morning sickness.
The Duchess is pregnant with her third child, a sibling for Prince George and Princess Charlotte.
Kensington Palace said Catherine was feeling "better, but she's still suffering".
The royal couple met children helped by the charities, as well as Paddington star Hugh Bonneville.
